Description

Technical Field

[0001] The utility model relates to the technical field of power equipment, in particular to an anti-condensation ventilation electric cabinet. Background Art

[0002] Distribution cabinets (boxes) are divided into various types such as power distribution cabinets (boxes) and lighting distribution cabinets (boxes). Low-voltage and high-voltage distribution cabinets in power distribution cabinets are relatively common. A high-voltage distribution cabinet refers to an electrical product that plays functions such as switching on and off, controlling, or protecting in the power generation, transmission, distribution, power conversion, and consumption of the power system, with a voltage level of 3.6 kV to 550 kV. It mainly includes several categories such as high-voltage circuit breakers, high-voltage disconnectors and earthing switches, high-voltage load switches, high-voltage automatic reclosing and sectionalizers, high-voltage operating mechanisms, high-voltage explosion-proof distribution devices, and high-voltage switch cabinets. It is the end equipment of the power distribution system. The low-voltage distribution cabinet is similar to the high-voltage distribution cabinet and can adopt manual control or computer automatic control methods, with functions of temperature regulation and self-monitoring. For example, Chinese Patent CN113964678A discloses a distribution cabinet with a temperature regulation function, including a distribution cabinet. A heat dissipation device is arranged inside the distribution cabinet. The heat dissipation device includes a heat dissipation pipe. The top of the heat dissipation pipe is fixedly installed on the top of the distribution cabinet. The lower half of the heat dissipation pipe is in a plastic elastic shape. A heat dissipation fan is rotatably installed on the inner wall of the heat dissipation pipe. The rotating shaft of the heat dissipation fan is connected to the rotating shaft of a disc through a belt drive. The disc is rotatably installed on the inner wall of the top of the distribution cabinet. A cylinder is fixedly installed at the bottom of the disc. The cylinder is slidably installed at the forked end of a forked rod. In this distribution cabinet with a temperature regulation function, by setting a heat dissipation device, when the distribution cabinet is cooled by the heat dissipation fan and the heat dissipation pipe, the forked rod can drive the lower half of the heat dissipation pipe to swing, thereby increasing the heat dissipation range of the heat dissipation pipe and effectively solving the problem of insufficient heat dissipation. However, due to the harsh use environment, large temperature differences, and high humidity, the cabinet made of steel is prone to condensation on the inner wall of the electric cabinet due to temperature differences. At the same time, the refrigeration equipment used in the electric cabinet is also prone to cause condensation inside and outside the electric cabinet due to temperature differences. The generation of condensation will seriously threaten the use stability and safety of the electrical components inside the electric cabinet, resulting in production stoppage. In severe cases, it will even cause a fire and cause heavy losses.

[0003] Therefore, it is necessary for those skilled in the art to provide an anti-condensation ventilation electric cabinet to isolate the temperature difference inside and outside the electric cabinet, reduce the humidity inside the electric cabinet, prevent condensation inside the electric cabinet, and improve the use stability and safety of the equipment.

Detailed implementation mode

[0017] Now, the present utility model will be described in detail with reference to the attached drawings. This figure is a simplified schematic diagram, which only illustrates the basic structure of the present utility model in a schematic way, so it only shows the components related to the present utility model.

[0018] Please refer to Figure 1 , the present utility model provides an anti-condensation ventilation electric cabinet, which includes an outer housing 10. The outer housing 10 has a square shell-like structure. The wall body 11 of the outer housing 10 is made of a combination of double-layer aluminum alloy and foam. The wall body 11 surrounds the four side walls of the outer housing 10. A door (not shown in the figure) is provided on the wall body 11. The wall body 11 is made of aluminum alloy, foam, and aluminum alloy from the outside to the inside. The foam is used as a sandwich to reduce weight and insulate heat.

[0019] An inner cavity 12 is formed inside the outer housing 10. The electrical components are installed in the inner cavity 12. An equipment platform 13 is provided outside the outer housing 10. A refrigeration equipment 27 is provided on the equipment platform 13. The refrigeration equipment 27 includes, but is not limited to, an air conditioner. The main unit of the air conditioner is installed on the equipment platform 13, and the indoor unit of the air conditioner is installed in the inner cavity 12 of the outer housing 10 to introduce cold air into the inner cavity 12 and reduce the temperature in the inner cavity 12 to ensure the stable use of the electrical components.

[0020] Furthermore, a duct group 20 is provided on the outer housing 10. The duct group 20 is arranged on the top of the outer housing 10 and is fixedly connected to the wall body 11. In the present utility model, the duct group 20 and the wall body 11 are assembled into one body to ensure the stability of the connection.

[0021] The duct group 20 includes an upper heat insulation layer 23, a lower heat insulation layer 24, and a ventilation layer 25 located between the upper heat insulation layer 23 and the lower heat insulation layer 24. A plurality of exhaust ports (not shown in the figure) are evenly provided on the lower heat insulation layer 24. The exhaust ports penetrate through the lower heat insulation layer 24 and communicate with the ventilation layer 25 and the inner cavity 12.

[0022] The cold air exhaust port of the refrigeration device 27 communicates with the ventilation layer 25. Specifically, the indoor unit of the air conditioner is installed in the ventilation layer 25, and the cold air exhaust port of the indoor unit communicates with the ventilation layer 25. During use, the refrigeration device 27 is used to introduce cold air into the ventilation layer 25, and finally the cold air is evenly introduced into the inner cavity 12 through the exhaust port, ensuring that the temperature of the working environment of the electrical components is controlled, reducing the temperature difference, and improving the use stability.

[0023] In the present utility model, the top of the entire outer housing 10 is provided with ventilation equipment, ensuring the uniformity and stability of ventilation. At the same time, a heat insulation layer 23, a lower heat insulation layer 24, and a ventilation layer 25 are provided on the top of the electric cabinet where heat absorption is easy and the lighting time is the longest, which can effectively reduce the influence of temperature and light on the interior of the outer housing 10, reduce the temperature difference, prevent condensation, and improve the stability and safety of equipment use.

[0024] In this embodiment, the upper heat insulation layer 23 is made of a combination of aluminum alloy and polystyrene board. Specifically, there are two layers of aluminum alloy, and the polystyrene board is arranged between the two layers of aluminum alloy. The polystyrene board is a roof panel formed by mixing crushed polystyrene foam plastic and cement, which not only has the effects of heat insulation and temperature insulation, but also can waterproof and absorb water, and can absorb a part of the condensate water to ensure the dryness of the interior of the outer housing 10.

[0025] In this embodiment, the lower heat insulation layer 24 is made of a combination of aluminum alloy and clay. Specifically, there are two layers of aluminum alloy, and the clay is arranged between the two layers of aluminum alloy. Due to the large number of pores in the clay, when the temperature difference is large and moisture returns or condensate water is generated, the surface layer with clay will temporarily absorb a small amount of condensate water. When the air humidity is small, the water can evaporate automatically, thereby preventing moisture and water vapor from entering the inner cavity 12 and preventing electrical components and other equipment from being damaged, improving the use stability of the equipment.

[0026] Furthermore, a plurality of inner cabinets 14 are provided in the outer housing 10. The electrical components and the computer are installed in the inner cabinets 14. The inner cabinets 14 are in a shell-like structure with one open side. The open side of the inner cabinets 14 is used to facilitate the installation of electrical components. A suction duct 15 is provided at the top of the inner cabinets 14. One end of the suction duct 15 penetrates the wall of the inner cabinets 14 and extends inward, and the other end of the suction duct 15 penetrates the wall 11 of the outer housing 10 and extends outward. A fan (not shown in the figure) is also provided at one end of the suction duct 15 located inside the wall 11. The hot air in the inner cabinets 14 is extracted by the fan to further reduce the temperature difference.

[0027] The electrical components include, but are not limited to, storage batteries. During the use of the electrical components and the computer, their bodies will generate heat. The cold air directly introduced into the inner cavity 12 will come into contact with the body of the electrical components and then generate condensation due to the temperature difference. The present utility model uses the exhaust duct 15 and the fan therein to specifically suck the hot air generated by the electrical components in the inner cabinet 14 during operation, reduce the heat of the body of the electrical components, thereby reducing the temperature difference, preventing condensation, and improving the use stability and safety of the present utility model.

[0028] The specific operation mode of the present utility model is as follows: use the exhaust duct 15 and the fan therein to suck the hot air in the inner cabinet 14, and at the same time use the refrigeration device 27 to introduce cold air into the ventilation layer 25, and finally evenly introduce the cold air into the inner cavity 12 through the exhaust port to ensure that the temperature of the working environment of the electrical components is controlled.

[0029] The present utility model is provided with an upper heat insulation layer 23, a lower heat insulation layer 24 and a ventilation layer 25 at the top of the electric cabinet where heat is easily absorbed and the lighting time is the longest, which can effectively reduce the influence of temperature and light on the interior of the outer housing 10, reduce the temperature difference, prevent condensation, and improve the use stability and safety of the equipment. At the same time, the electrical components arranged in the inner cavity 12 are controlled by multiple temperature control methods to reduce the temperature of the body of the electrical components and the ambient temperature, thereby achieving the purpose of reducing the temperature difference, preventing the generation of condensed water, and improving the use stability and safety.
